perf tools: Fix handling of wildcards in tracepoint event selectors
It wasn't accounting the ':' when consuming bytes in the the event selector string, so parse_events() would fail in this test: if (!(*str == 0 || *str == ',' || isspace(*str))) return -1; as *str would be pointing to '*', the last character in the '-e' arg in: $ perf record -q -a -D -e sched:sched_* | perf script -i - -s perf-script.py Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Mike Galbraith <efault@gmx.de> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Stephane Eranian <eranian@google.com> Cc: Tom Zanussi <tzanussi@gmail.com> LKML-Reference: <new-submission> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
